idpf: fix mismatched free function for dma_alloc_coherent 



The mailbox receive path allocates coherent DMA memory with
dma_alloc_coherent(), but frees it with dmam_free_coherent().
This is incorrect since dmam_free_coherent() is only valid for
buffers allocated with dmam_alloc_coherent().

Fix the mismatch by using dma_free_coherent() instead of
dmam_free_coherent
